Camera preview is letterboxed when on portrait

问题:

I'm using the cameraPreview sample coming with the Android API demos. The problem is, the camera preview is showing properly on landscape, but when I rotate the phone to portrait, I get a letterboxed and rotated image.

I'm using Android 2.3.3 and a Samsung Galaxy Ace, but also tried 2.1 on a Xperia Mini 10 Pro.

A couple of pics (sorry for poor the quality): portrait http://i42.tinypic.com/a9qzuu.jpg

Is this normal behavior of the demo program? What's a proper way to fix it?

回答1:

This helped for me :

mCamera.setDisplayOrientation(90);

I was able to fix the problem I was having that was very similar to this. It had to do with with an old supports-screens ... / entry I had in my manifest file. I removed this from my manifest and everything worked like a charm. Hopefully this might help solve your problem. Cheers.

Solved it, turns out it was a problem with my manifest, I had to include a line defining a fixed screen orientation for the camera activity. :P
